research labDateTopic The reactivity seriesProblem Which of the following metals atomic number 18 more labile with acids magnesium, zinc, aluminum, iron, lead, and copper?Hypothesis Aluminum is the most reactive with acids beca spend it occurs in group III.Aim To perform a comparative examination on which metal is the most reactive with acids.Experiment A comparative test is done exploitation time to find which metal has the speedy response Skill P & DApparatus Equipment 1. 6 beakers2. water3. Measuring cylinder4. Watch or ClockMaterials 1. Aluminum botch2. copper color coin3.Lead pellets4. surface from a battery5. Magnesium from Antacid6. Iron ShavingsReagents 1. HCl performance 1 Rinse the containers with distilled water.2. Pour 25cm3 of HCl in each beaker by use of measuring cylinder.3.Insert each of the dissimilar sample metals into a beaker one at a time.4.Observe and record the amount of time before the reaction lettuce with clock.5. Make a table of your observat ions.6. Setup a control using water as the reagent.Variables Independent Aluminum foil, Copper coin, lead pellets, Zinc from a battery,Magnesium from Antacid, and Iron Shavings.Dependent response Time get overled HClControl This is an identical experiment using water as your reagent.Data The reaction time for the different metals , to show which is the most reactive in acids.MetalsReaction Time/seconds in acids.MagnesiumAluminumZincIronCopperPrediction Aluminum will be the most reactive because it is in group 3 which has the least amount of electrons to loose.Results The results for reaction time of the different metals, to show which is the most reactive in acids.
